Thinking transparent reconnects of applications is the grail of HA? It is! But Active/Active setups make them risky.
Sometimes you really, really want to know what a MySQL client is asking of the MySQL server. As of Tungsten Clustering v7.0.0, you may now enable Connector Audit Logging, which captures data transferred between client applications and MySQL servers to a file, database or socket. This blog post will walk you through the feature and how to enable, configure and disable Tungsten Connector Audit Logging.
We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.17 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.
SmartScale is a special mode of the Tungsten Connector (aka Tungsten Proxy), which allows read requests to be intelligently routed to either a replica or the primary to ensure that the data returned is not stale. This feature is available when the Connector is running in the application-layer Proxy mode. Learn more about the behavior of SmartScale in this blog.
Customers often ask where they should install their MySQL, MariaDB, or Percona MySQL database proxies for high availability clusters, and how many. What is optimal for you may not be the right configuration for everyone. However there are some best practices we’ll discuss in this basic blog about deploying MySQL database proxies.
How the Continuent Proxy selects database cluster nodes for executing read operations.
In this short blog post, we examine the impact that setting the Tungsten cluster policy to Maintenance has on the cluster behavior, and specifically the impact on the Tungsten Connector.
This blog provides basic information about business-critical application to database connections; my team focuses on MySQL, MariaDB, and Percona Server for MySQL on Linux/Unix that’s infrastructure-agnostic (on-prem, VM, hybrid-cloud, cloud, multi-cloud, etc.).
Learn how and where the Connector communicates, and about the different SSL configurations possible.
View this presentation to learn about two types of (MySQL) database proxies, which we refer to as ‘fast & simple proxy’ and ‘intelligent proxy’; and how transparent failover and read-write splitting works for these.
